Changed out my RODI prefilters today. Every 6 months even if it may not need it. Vendors say 6-12 months for carbon blocks and as pressure drops for sediment filters. Manufacturers spec out certain volume amounts at certain rates for carbon filters.
Since I'm not tracking volume amounts I figure every 6 months even if not needed is cheap insurance to keep the membranes healthy. I change out the membranes every 3 years even if some say they can go longer. Again, cheap insurance for clean water for my tank.
For the prefilters I have a reminder setup in Neptune's Fusion now but other wise every January and June. Membranes I just remember any year divisible by 3 which will be next year.
This time around I went with a 1 micron sediment, 1 micron carbon, and .6 micron carbon stages. Before I had 5 micron, 5 micron, .6 micron.
